The downside to injecting from below is your better off with a second pair of hands because when you pull the tube nozzle out, it wants to squirt out right away. Have some silicone plugs nearby to stop it from flowing out right away, put down drop cloths and wear old nasty clothes you want to thow away! The stuff is STICKY! Don't ask how i know... :)
That said I think the solvent is mineral spirits which works pretty well.
